` dinard 51am t. aient @imita JESSE JENKINS, OE ANDREW COUNTY, MISSOURI, .ASSIGNOR FOR ONE- HALF TO ABRAM DOBBS, OF SAME PLACE.

Letters Patent No. 95,906, (lated October 19, 1869.

The Schedule referred to in these Letters Patent and making part'of the same.

To all whom 'it may concern Be it known that I, JESSE JENKINS, of Andrew county, in the State of Missouri, have invented a new and useful Improvement in a Planter, Oultivator, and Roller, combined; and I do hereby declare thatthe following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, andletters of reference marked thereon, 'making a part of this specification, in which- Figure l is a plan view, and

Figure 2 is a longitudinal central vertical section.

To enable those skilled in the art to make and use my invention, I now proceed to describe its construction and operation.

Similar letters in the drawings referto-like parts.

This invention consists in connecting, with the dropapparatus of a planter, a peculiar mechanism for disconnecting it from its motive-power, at anytime it may he required to arrest the deposit of seed. Also, in connecting with the driving-wheel of a planter-apparatus, a mechanism for preventing said wheel from revolving during the turning of corners, so as to arrest the deposit of seed at such times. Also, in the general combination of the several above-named parts.

In the drawingsa' a are the seed-boxes, through which play the Adouble drop-slides a', between each pair of which, at

the forward end, is pivoted the plate a", the latter being joined, by connecting-rods b, with the cranks b", in the shaft b', the latter being rotated, and consequently giving motion to the slide, by means of Athe cog-gearing d d', the wheel d' fastened upon the end of the said shaft, and the wheel d, rigidly connected withv the main wheel A".

Between the wheel d'` and the crank b, nearest it, the shaft passes across the pivoted standard c, and lies in a groove in the same.

Thestandard is pivoted, as seen in fig. 2, to the frame A, by means of an. oset, o, extending d own into a slot in the frame.v

A handle, c, rises from the. standard c, and passes through a slot made lengthwise of the horizontal guide-frame c', which slot has small offsets s in one side, in either of which the spring-plate c3 tits, which spring-plate is attached, at its lower end, tothe standard c. The conjoint operation ofthe oset and spring locks the standard.

On removing the spring from the offset, there is nothing to prevent throwing the standard c back on its' pivot o, and thus raising the shaft b', till the cogwheel d is separated from the cog-wheel d, when the operation of the planting-apparatus is arrested, until such time as the cog-wheels d d' are brought together again, by restoring the lever to its former position.

The pivoted standard is intended especially for use when, in moving straight forward, it is desirable to prevent the planting-apparatus from acting, as in going from place to place in fields or on roads.

In iig. 1, h is an iron rod,'passing through -the frame-work A, opposite the rim of thewheel A".

Ihere is a hole in the latter, into which the end of the rod h1nay be made to enter, by moving in the proper direction the lever h', pivoted across the axle A, which movement is effected by the handle ha, piv.

oted in the inner end of the beam it, projecting inward from the side of the frame.

The lower end of the handle is jointed to the rear end of the lever 71.', and its movement from right to left causes the rod h to enter the wheel and stop its revolution.

The shaft b ceases to revolve when the wheel A does, and the stoppage of' the planter-apparatus follows.

The brake-mechanism is designed to bel used in turning corners, when it is not necessary that the wheel A should rotate.

.vlhe frame Ahas a shaft, D, attached to itsI rear end by slotted holders i, so that the shaft can rise or fall, as necessary.

- Rollers D are placed upon the shaft, exactly in the rear of the seed-boxes a and cultivator-shovel'sfr lr, which prepare the drill and cover the seed. The rollers follow, and smooth down the ridge.

C C' are shafts, placed crosswise of the frame, to which shafts the shovels r c' are connected.

B is another shaft, in the front part of the frame, having arms-7c projectingdownward from its lower side, to which arms are jointed the front ends of the rods m n, the latter being jointed at their rear ends to the shovel-supports. By rotating the shaft B, the shovels are lifted out of or returned into the soil.

What I claim as new, and desire to secure by Letters Patent, isf

l. The combination of the seed-box a, slide a', shaft b', Awith the pivoted standard c, spring c, and slotted.

guide-frame c', all arranged and operating substantially as described.

2. 'lhe combination, with the seeder-irame, of the lever It, rod h, and handle h', in the manner and for the purpose set forth.

3. Ihe combination of shaft and rollerD D with the shafts and shovels C C lr, controlling-shaft B,

-planter-apparatus a, a', crank-shaft b', disconnectingvapparatus c c' c c, and brake-mechanism h It" h3, all

arranged and operating in the manner explained.
